firf/zur 6E Ping/en United States Patent 3,326,408 PLASTIC BOX CONTAINERArthur G. Ringlen, 1008 Ave. K, Brooklyn, N.Y. 11230 Filed Feb. 24,1965, Ser. No. 434,802 1 Claim. (Cl. 220-60) This invention relates tocontainers and more particularly to an all plastic shallow box with aremovable cover.

An object of the present invention is to provide an elongated shallowplastic box and cover, the box body and cover adapted to be nested andstacked interchangeably for ease in use and disposal.

Another object of the invention is to provide a plastic box having abody with means for preventing the box bodies from sticking togetherwhen stacked.

A further object of the invention is to provide a plastic box and coverhaving stiffening ribs.

Still another object of the invention is to provide a plastic box ofthis kind with improved means for holding the cover on the box body.

It is also proposed to provide a plastic box of this kind that is simplein construction, economical to manufacure and attractive in appearance.

For further comprehension of the invention and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings and to the appended claim in which the variousnovel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIGURE 1 is a top perspective view of a box embodying the invention, thecover being shown in closed position,

FIG. 2 is a top perspective view of one half of the box with the covershown removed from the box body.

FIG. 3 is a vertical sectional view taken on the line 313 of FIG. 1,with the cover removed, on an enlarged sca e,

FIG. 4 is a vertical sectional view taken on the line 44 of FIG. 1, onan enlarged scale,

FIG. 5 is an enlarged bottom plan view of one corner of the cover,

b SIG. 6 is a top plan view of one corner of the box FIG. 7 is avertical sectional view taken on the line 77 of FIG. 1, the coverbeing'shown removed, on an enlarged scale,

FIG. 8 is an end elevational View of several boxes of FIG. 1 in stackedrelation,

FIG. 9 is an enlarged vertical sectional view taken on the line 99 ofFIG. 8, and

FIG. 10 is a horizontal sectional view taken on the line 1010 of FIG. 1,on an enlarged scale.

Referring now in detail to the various views of the drawings, in FIGURE1 a box made in accordance with the invention is shown and designatedgenerally at 10. The box 10 is formed of suitable sheet plastic materialof the thermo-plastic or the-rmosetting type and may comprise plasticsof the phenolic, urea, cellulose-acetate or other type of syntheticplastics which may be moulded or extruded. The material may be anythickness, from wafer thin upwards.

The box 10 comprises an elongated one-piece body or base 12 andone-piece removable cover 14. The box body or base 12 and cover 14 maybe opaque, transparent or translucent.

The box body or base 12 is rectangular in shape and shallow with abottom wall 16, downwardly and inwardly slanting side walls 18, 18 anddownwardly and inwardly slanting end walls 20, 20 and is open at thetop, as viewed in FIGS. 1 and 2. The top edges of the side and end3,326,408 Patented June 20, 1967 walls are formed with a continuousoutwardly extending flange providing a seat 22 for the cover 14. At itsouter edge, the flange 22 extends perpendicularly or upwardly as viewedin FIGS. 1 and 2 forming an upwardly extending continuous flange 24, andthen continues into a slightly outwardly slanting flange 26.

In accordance with the invention along the upright flange 24 outwardlyof the side walls 18 of the box body or base 12 there are instruckintegral lugs 30, 30 and outwardly of the end walls 20 there are similarinstruck lugs 32, 32. A space 34 is provided undernearth each lug.

Furthermore, in accordance with the invention spaced along the sidewalls 18 and end walls 20 there are a plurality of instruck verticalribs 36 as viewed in FIGS. 1 and 2 extending from the seat 22 downwardlyand inwardly to the bottom wall 16 and intersecting the juncture betweenthe bottom wall and side and end walls.

The plastic cover 14 is constructed similarly to the body or base 12 andis approximately of the same dimensions having a base or bottom wall 40,inwardly slanting side walls 42, 42 and end walls 44, 44, with theinstruck ribs 46 and 48 thereon, respectively. An outwardly extendingintegral flat flange 50 extends around the outer edges of the side andend walls. 2

In use, the cover 14 closes the open top of the body or base 12 byinverting the body or base 40 and pressing the flange 50 downwardly ontothe seat 22 on the base 12, the edge of flange 50 snapping over thelocking lugs 30 and 32 into the spaces 34 therebelow therebyinterlocking the cover on the box body. The cover 14 can readily beremoved by manually squeezing the sides 18-, 18 of the box body andlifting the cover off of the body.

The box body 12 and the cover 14 may be readily nested with the coverinside the box body for use and disposal, and the nested units may bereadily stacked, opening upwardly as shown in FIGS. 8 and 9, with theflanges 22 of the box bodies seating on the flanges 50 of the covers 14as best seen in FIG. 9.

By reason of the stacking lugs 30 and indentations constiuting the ribs36, the box bodies or bases 12 may be readily stacked on top of eachother, independent of the covers 14, as shown in FIGS. 9 and 10, beingnested in spaced relation preventing binding and permitting easy removalof the top body or base from the stack.

The covers 14 may also be stacked on top of each other, independent ofthe box bodies or bases 12, by means of the identations constitutingstacking ribs 42. When so stacked, the covers can be readily removed oneat a time.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself to theprecise constructions herein disclosed and that various changes andmodifications may be made within the scope of the invention as definedin the appended claim.

Having thus described the invention, what I claim as new and desire tosecure by United States Letters Patent 15:

An all plastic box comprising an elongated shallow body rectangular inconfiguration having slanting side and ends walls, said side and endwalls terminating in a continuous outwardly extending flange therearoundforming a seat, and said seat continuing into a perpendicularlyextending flange, and a removable cover on said seat, said cover havingoutwardly slanting side and end walls, terminating in a continuousoutwardly extending flange therearound adapted to seat on the flange onthe side and end walls of the body and spaced instruck lugs on theperpendicularly extending flange adjacent the seat adaped to interlockwith the flange on the cover for holding the cover on the body, andspaced ribs instruck in the side and end walls of the body and cover,said ribs h V 3 1 4 V extending from the flanges on the body and cover t3,065,875 11/1962 Negoro 22060 the juncture of the bottom walls and sideand end walls 3,104,776 9/ 1963 Bostrom 22072 thereof.
